Craft CMS redirects requests that require authentication to the login page and generates a session file on the server at \u0027/var/lib/php/sessions\u0027. Such session files are named \u0027sess_[session_value]\u0027, where \u0027[session_value]\u0027 is provided to the client in a \u0027Set-Cookie\u0027 response header. Craft CMS stores the return URL requested by the client without sanitizing parameters. Consequently, an unauthenticated client can introduce arbitrary values, such as PHP code, to a known local file location on the server. Craft CMS versions 5.7.5 and 4.15.3 have been released to address this issue."
